THROUGHOUT the world for many years concrete has 
played a most important part in construction. Yet 
authorities everywhere have recognized the need for 
improvement in concrete which would fortify it against the 
action of the elements — freezing and thawing, and other 
disintegrating influences. 

The Research Laboratories of The Master Builders Company 
recently announced to the construction industry a new 
principle— CEMENT DISPERSION. This principle was dis- 
covered ten years ago and incorporated in Pozzolith. A 
decade was devoted to testing and proving the efficiency of 
this product in the laboratory and in the field. 

The evidence of performance of Pozzolith has accumulated 
in an impressive and conclusive manner. This book sets 
forth some of this evidence on the "how" and "why" of 
Pozzolith. It shows representative installations and users. 






The application of the DISPERSION PRINCIPLE to cement 
increases the efficiency of all cement to which it is applied. 
This is a basic technologic advance in the cement field 
since it has long been recognized that only from 50% to 60% 
of the cementing value is utilized in concrete design because 
of incomplete hydration. [Anderegg & Hubbell A.S.T.M. 
29 II 554 (1929)]. Through dispersion of the cement, im- 
portant savings in initial costs, as well as maintenance costs 
are made for : 

(1) OWNERS ... by lowering first costs of construction and 
by reducing and deferring for many years the mainte- 
nance costs of their concrete structures. 

(2) DESIGN ENGINEERS ... by improving their control 
over the consistency, uniformity and quality of struc- 
tures they plan, and by providing a means of designing 
quality concrete economically. 

(3) CONTRACTORS ... by reducing material costs and 
placing costs through increased workability, easy and 
economical placement, protection from segregation and 
bleeding, resulting in reduced patching and rubbing of 
the concrete. 

Full technical data will be sent to those who desire more 
complete information.

WHAT IS POZZOLITH? 



POZZOLITH is a cement dispersing agent combined 
with a pozzuolanic carrier in the form of a fine gray 
powder. It is added to the concrete mix at the mixer. 
By deflocculating the cement particles it greatly increases 
the effective surface area of the cement, increasing the 
plasticity of the mix, and reducing the excess water re- 
quired for placing the concrete. 

The use of Pozzolith in concrete results in important 
functional, as well as structural advantages, as follows: 

1. Durability increased 50% or more 

2. High Early Strength— 20% or more Increase 
in Compressive Strength at all ages 

3. Water Reduction— up to 20% 

Slump Increased 150% or more for given 
water ratio 

4. Increased Water-tightness— 20% or more 
reduction in Absorption and Permeability 

5. Reduced Bleeding and Segregation 

6. Reduced Heat with Minimum Cement 
Content 



which means 

1 . Concrete of given strength at lower cost. 

2. Stronger and more durable concrete at a 
given cost. 



Pozzohth .made m two types-Standard and High Early. 
Hxgh Early Pozzohth provides all the advantages of Standard 
Pozzohth, plus h ig h early strengths; i.e., normal 3 day

Cement in water with 
Pozzolith added, show- 
ing dispersion. Magni- 
fied 300 times. 







Cement particles in their normal 
state in water tend to gather in 
bunches, i.e., flocculate. Water 
never reaches some particles and 
many are only partly hydrated. 
This reduces the effectiveness of 
the cement, entraps water within 
the clumps, requires an excess of 
water for placement and often re- 
sults in bleeding and segregation. 



With Pozzolith the dispersion 
principle operates to drive each 
particle apart, thus exposing all 
the cement particles to the vital 
hydrating action and consequently 
assuring increased efficiency. 



CEMENT DISPERSION 



* 



ONLY a part of the cementitious value of the cement, whether normal portland 
or high early, is utilized under usual construction conditions. Investigation 
shows that with 28 days curing only 50% of the cement hydrates. Even with 
90 days curing only 60% of the cement hydrates. {Anderegg and Hubbell, A.S.T.M. 
29 II 554 (1929)] 

Since the reactions on which portland cement depends for its valuable properties are 
surface reactions, it is obvious that a dispersing agent in the mix permits utilization 
of the cement to the full extent. Cement Dispersion applied through Pozzolith in- 
creases the degree of hydration of the cement from 30% to 40 r [ which is fully confirmed 
by the resulting increases in strength. 



Dispersion also produces a "buttery" or 
"fatty" condition in the mix, which is 
directly due to the attractive forces be- 
tween the greater surfaces. These at- 
tractive forces produce cohesiveness which 
in turn reduces the tendency of the mix 
to separate, that is toward segregation, 
and reduces or eliminates bleeding or 



water gain. Higher "water retentivity" in 
the mass is produced, which is important 
for proper concrete curing- 
Water held in the clumps is released to 
become part of the fluid through which 
the particles move. Thus the mix is made 
more workable, and more important, 
workable with less water content.

detail with the principle of dispersion of cement particles, will be sent you on request.

olith Increases Durability. 

By Reducing Water Up to 20% 

By Increasing Workability 150% 




Pozzolith increased the workability of "Pump -Crete", 
made placeability easier, on this Milwaukee job. 



DISPERSION of the cement particles 
through the addition of Pozzolith to 
regular portland cement increases 
the mobility or ease of flow, since water 
held in clumps of the flocculated cement is 
released to become part of the fluid medium 
through which the particles move. 

Consequently, for a required slump much 
less water is required. At equal "slump" 
the mobility of a Pozzolith Concrete mix is 
conspicuously greater than that of the cor- 
responding Plain mix. This reduction in 
water-cement ratio greatly increases dur- 
ability.

By Reducing Water Gain and Segregation 




By the use of Pozzolith, concrete can be poured with minimum water gain, thus reducing segregation. 



<■ 



'-, 



THE phenomenon which is called 
variously 'initial shrinkage', 'bleed- 
ing', 'water gain', or 'settling', is the 
displacement in the vertical direction of the 
solids downward and the water upward. As 
a direct consequence of the reduced water 
content and increased cohesiveness pro- 
duced by Pozzolith, this action is reduced 
or eliminated, as are the formation of 
laitance and planes of weakness at the tops 
of pours.

Report of Permeability tests of Plain and Pozzolith concrete by Rush Engineering Co., Chicago, Illinois. Tests included 
three types of concrete: (I) Plain "6-sack" concrete; (2) Pozzolith "6-sack" concrete; and (3) Pozzolith "5-sack" concrete. 

By eliminating up to 33% of 
the excess water from the 
mix, Pozzolith directly at- 
tacks the big cause of leakage. 
Permeability and absorption 
are reduced. Note that mix 
"D" with same placeability as 
mix "A", and of substantially 
the same cost, is more water- 
tight, despite 94 lbs. more 
cement per yard in mix "A".

The above graph and photographs from report of tests 
made at a leading University show increase in durability 
of Pozzolith concrete from 100 ( ( to 200 r ( over that of 
corresponding plain mix. (Detailed report sent on request.) 



The Durability of Concrete is measured by its re- 
sistance to freezing and thawing. Freezing and 
thawing tests made in the laboratories of leading 
universities and institutions prove conclusively 
the far greater durability of Pozzolith Concrete. 

Many concrete structures are exposed to sea 
water, alkali soil, corrosive solutions formed from 
acid impurities in the air, from various soluble 
compounds in nature or from industrial processes, 
all highly destructive agencies. Pozzolith in- 
creases very substantially the life of concrete sub- 
ject to these destructive agents by making strong- 
er, more water-tight concrete, plus reduced solu- 
bility due to pozzuolanic action. 



Plain concrete after 150 cycles of freezing and 
thawing lost 73% by weight.

By Increasing 

Strength 25% 





STRENGTH of workable 
mixes is governed by the 
water-cement ratio law 
and the surface area available 
for hydration. Since Pozzolith 
reduces the water-cement ratio 
up to 20%, and by dispersing the 
cement particles makes greater 
surface area available, it auto- 
matically increases the strength 
by at least 20% over that of plain 
concrete of same design and 
slump. Field reports show this 
increase actually averages 25' { 
or more.

The above stack was built in the same year, 1936, by the same builder, Custodis Canadian Chimney 
Company, using the same mixes and methods, except for the use of Pozzolith in Port Colborne stack 
(opposite page). Slump of the concrete in both jobs was the same: averaging 3 inches. Note Strength of 
Pozzolith Concrete averages 25% higher.

Pozzolith Increases Durability . . . 

By Avoiding Excess Cement Content and Excess Heat 



FLOCCULATION of cement particles nor- 
mally makes the use of excess cement and 
water necessary to produce workability. 
The use of this excess cement paste results in in- 
creased heat evolution and increased volume 
change with their tendency to produce cracks.

Temperature rise adiabatic for two normal cement 
mixes, one a dispersed cement mix containing 3.2 
sacks cement per cu. yd., the other an undispersed 
mix with 0,8 sacks additional cement. Excess cement 
has the undesirable effect of increasing heat evolu- 
tion and temperature rise. 



By taking full practical advantage of the potential 
value of cement, the dispersing action of Pozzolith 
makes concrete mixes of low cement content 
readily placeable. It diminishes the heat evolu- 
tion by making excess cement unnecessary and 
thereby reduces volume change, checks cracking, 
and so produces more durable,* water-tight** 
concrete. 



*See Freezing and Thawing and Corrosion Tests, Page 21, which show Pozzolith concrete is more re- 
sistant than plain concrete containing excess cement and water. 

**See Rush Laboratory Report Page 11, which shows a 5-sack Pozzolith concrete to be more water-tight 
than the plain concrete containing excess cement and water.

STRENGTH— Dispersion will produce at 
any age strength equal to or greater than 
that obtained through the addition to 
the mix of one extra sack of cement in the usual

mixes. 



Since the cost of using dispersion is less than 
that of using one additional sack of cement, for 
a concrete mix of given strength, the most eco- 
nomical mix design will be secured by designing 
the mix with Pozzolith. 

High Early Strength — High Early Pozzolith with 
normal portland cement will give Early Strengths 
comparable to those secured by using high 
early strength cements and greater than by using 
one additional sack of normal cement, and 
hence will substantially lower cost of materials.

DISPERSION of the cement increases 
the mobility or fluidity of the con- 
crete. When mobility is increased 
the concrete flows more readily and is 
compacted more easily. The concrete is, 
therefore, dumped from mixers, trucks, 
buggies, and moved into place with less 
labor. Less labor is required for compact- 
ing, filling in around reinforcing, and 
other operations involved in placing the 
concrete where it is wanted. 
With a more workable concrete better 
surfaces next to forms are secured. Less 
rubbing and finishing are required to put 
these surfaces into good condition where 
appearance is a factor. 

Dispersion improves the cohesiveness of 
the mix so that there is less tendency 
toward segregation, honeycombing, sand- 
streaking and similar defects due to segre- 



gation. The greater ease of placing and 
compacting also reduces the amount of 
similar defects due to failure to secure 
complete filling and compacting at all 
points. The reduction of these defects 
reduces the labor required for patching, 
repair and finishing. 

In short, dispersion of the cement in a 
concrete mix permits savings to be made 
in the initial cost of the concrete in place 
by reducing the labor of placing and fin- 
ishing. These reductions in labor costs 
are secured without increase in materials 
costs in practically all cases, at lower 
materials costs. In certain types of work 
where labor costs are more important 
than material costs, large economies in 
labor can be made by using Cement Dis- 
persion at small added material cost^ 
giving a substantial net saving.

AFTER 2 YEARS IN 8% MAGNESIUM SULPHATE 

b. Resistance to corrosion — Dispersion pro- 
duces markedly higher resistance to sul- 
phate waters than one additional sack of 
cement. 

Dispersion greatly enhances the durability of the concrete mix at 
no additional material cost. With increased durability there can be 
little question that under any given conditions the cost of mainte- 
nance will be materially decreased and the serviceable life of the 
structure, before replacement is required, will be substantially 
prolonged.

Pozzolith Utilizes Dormant Cement 

To Create This 

Saving Zone 

WHATEVER Your Concrete 
Requirements are — whether 
they be for low strength or 
high strength, for a 5-year shed or a 
50-year dam — you produce them 
at Lower First Cost with concrete 
designed and built with Pozzolith. 
In addition, subsequent costs for 
Maintenance are lower. 

Specify 

1 'All concrete mixes shall be designed 
with Pozzolith" to assure getting 
the full increase in durability and 
the full initial savings produced by 
Cement Dispersion.

WHAT USERS SAY... 



EAST CHICAGO, INDIANA WATERWORKS 

"... by using Pozzolith we were able to reduce the water 
content of the mixture by 20^1 thereby effecting a sufficient 
saving on cement to offset the cost of Pozzolith. We also 
found easier placement of concrete, which meant a saving in 
labor, and finally, the concrete so placed was very dense and 
water-tight/' 

H. B. OLNEY, INC., East Chicago, Indiana 



VALDESE, NORTH CAROLINA 
WATER PURIFICATION PLANT 

". . .it was possible to reduce the water ratio approximately 
three quarts per batch ... as well as effecting a saving of 
approximately eight per cent . . . The workability of the 
mixed concrete with Pozzolith, was far superior than had 
we used the required amount of cement and water," 

BOYD & GOFORTH, INC., Charlotte, North Carolina 



MISSOURI STATE PENITENTIARY, 
JEFFERSON CITY, MISSOURI 

"The concrete flowed perfectly, with a minimum of placing 
labor and gave a splendid appearing surface when the forms 
were removed." 

GEO. E. McINTYRE, Jefferson City, Missouri 



"Using the Pozzolith has also made a difference in keeping 
both pallets and block machine free of excess materials. That 
in itself is a great saving in labor/ 7 

CRAWFORD BUILDERS SUPPLIES, Port Huron, Michigan 



GARY, INDIANA SEWAGE TREATMENT PLANT 

"The addition of Pozzolith increased the workability and 
plasticity of the concrete with no increase in the water 
cement ratio, greatly facilitating the placing and finishing 
operations/' 

PERMANENT CONSTRUCTION CO., Chicago, Illinois 



BANKERS LIFE BUILDING. DES MOINES, IOWA 

UNITED BENEFIT LIFE INSURANCE BUILDING, 

OMAHA, NEBRASKA 

"In addition to the permanent improvement in the quality 
of the concrete through the use of less water, contractors 
advise us that they are able to place Pozzolith concrete more 
easily and obtain a better appearing job." 

TINSLEY, McBROOM & HIGGINS, Des Moines, Iowa 



KANSAS CITY, KANSAS LEVEE ELEVATOR 

". . . The addition of Pozzolith has maintained the desired 
slump with a reduced amount of water and has given a con- 
crete easy to place with the minimum of labor."

MANSFIELD (OHIO DISPOSAL PLANT 

v, In the specifications for the Mansfield Sewage 
Disposal Plant where approximately 3500 cubic 
yards of reinforced concrete was used in compara- 
tively thin sections, I specified that the concrete 
l shall contain an admixture for the purpose of pro- 
ducing a dense waterproof concrete of high strength 
yet having sufficient plasticity for easy placing.' 

*The specifications called for a material capable 
of combining with calcium hydroxide to form a water 
insoluble compound. The material specified was 
Pozzolith as supplied by the Master Builders Com- 
pany or its approved equal. 

"I have not seen a finer piece of concrete work 
than the contractor produced on the Mansfield 
Sewage Disposal Plant. Not one area of honey- 
combed concrete showed on the surface and no ex- 
cessive amount of puddling was required. The con- 
crete had a considerably higher strength than that 
specified and I am sure that the contractor was well 
pleased with the results."

Architect— Private Plans, Contractor— Ford J. T waits Co., Los Angeles, California. 

"In the construction of this project we used POZZOLITH which was manufactured by you. 
This material was used in all of the exterior concrete work. 

We found that it produced excellent results in reducing quantity of water in the con- 
crete and still maintained the desired slump. 

The exterior concrete was employed for architectural treatments and we obtained an 
architectural result which was almost entirely free from patching after the stripping 
of the forms. 

We found on this work that POZZOLITH fulfilled every claim which you made for it."

piffled, xm& SpsecifjicatiawL 



POZZOLITH is made in two types — Standard and High 
Early. High Early Pozzolith provides all the advan- 
tages of Standard Pozzolith, plus high early strengths; 
i.e., normal 3 day strength in 1 day, normal 7 day strength 
in 3 days, normal 28 day strength in 7 days. 
Both types are produced in highly concentrated form, pro- 
viding maximum dispersion and maximum economy. 



STANDARD POZZOLITH
